Opinion: Also, HTC has this reputation for using really low capacity batteries, and people complain that they wear out pretty quickly. Try a new battery or an after-market one with extended life. Still will want to use the battery stats wipe though.

Could you suggest what battery I can use? I have no idea what "extended life" means. Also ... can I change 15% to some other number?

Not sure you can change 15%. The "extended life" battery is an after-market battery of a different size. You'll probably need to get a different back cover for the phone.

I did the battery wipe and full charge (mobile was turned on) then used till battery ran out and now the phone shuts down at 20% ... :-( The battery is one year old.

That's...amazing. I'm out of ideas, beyond doing the same thing but not wiping this time.
